IPC: A47B9/02
Filed: 1997-12-11
Granted: 2007-04-17
Abstract: A height adjustable workstation uses a torsion spring in association with a transmission for providing a counterbalance force opposing downward forces applied to the work surface. The workstation has telescoping legs and the telescopic movement thereof is transmitted through the transmission system to the torsion spring. The torsion spring is loaded and applies the counterbalance force to the legs via the transmission. The system includes a hand engaging adjustment mechanism for varying the magnitude of the counterbalance force and also includes a lock arrangement for locking the workstation at various selected positions. The preferred transmission system includes a rack and pinion gear arrangement connected to the torsion spring by a shaft.

Patent CA-2251803-C (CA)

Granted: 2003-07-08
Abstract: Chemiluminescent detection of molecules of synthetic or natural origin such as proteins and nucleic acids (DNA and RNA), as well as other biologic molecules, is increasingly replacing radioactive detection as the method of choice where sensitivity is critical. In such assays, luminescence is customarily achieved by the oxidation of a luminol or isoluminol substrate in the presence of an oxidizing agent such as hydrogen peroxide or hydrogen peroxide source, such as perborate, and a peroxidase catalyst such as horseradish peroxidase. To obtain useful levels of luminescence (e.g., detectable levels) by customary techniques, a luminescent enhancer is also present during oxidation. It has been found in the practice of the present invention that azine enhancers have contained an impurity which reduces the properties of the chemiluminescent assay working solutions. The present invention describes a working solution, a process of using the working solution, and kits containing solutions which can be mixed to form the working solutions comprising a solution which is useful for the chemiluminescent assay of peroxidase activity comprising: a) at least one chemiluminescent cyclic diacylhydrazide, b) at least one azine enhancer, and c) at least one oxidizing agent wherein said azine enhancer comprises less than 0.005 parts mole/mole total basis of azine compounds having a hydrogen atom bonded to a nitrogen atom of the azine ring. It has generally been found that this hydrogen containing azine is a poisoning agent for the performance of the azine enhancer.

Title: Dynamic binding and bridging in a communication system
Inventor: BAKER ALBERT D
IPC: H04W88/14
Filed: 1999-01-28
Granted: 2002-11-19
Abstract: The invention provides dynamic binding and bridging between a mobile terminal and other more complex terminals in a communication system. In an illustrative embodiment, a temporary association is established, in a memory of a system switch, between the mobile and at least one other system terminal. While the mobile is "registered" in this manner to the other terminal, the mobile user can request permission to utilize the functions of the other terminal in order to, for example, receive incoming calls or place outgoing calls. The temporary association may be established based on a determination of the proximity of the mobile to the other terminal, such that the mobile registers to different complex system terminals as it moves between different cells of the system. The invention also provides techniques which allow users to access a user-defined profile for one terminal at another terminal of the system.

Title: Photocatalytically hydrophilifiable coating composition
Inventor: HAYAKAWA MAKOTO
IPC: C09D183/02
Filed: 1997-07-16
Granted: 2007-06-26
Abstract: A composition is disclosed which can hydrophilify the surface of a member to impart an antifogging property to the surface of the member. The composition for hydrophilifying the surface of the member comprises at least (a) photocatalytic particles of a metallic oxide, (b) a precursor capable of forming a silicone resin film or a precursor capable of forming a silica film, and (c) a solvent, the total content of the photocatalytic particle and the solid matter of the precursor in the composition being 0.01 to 5% by weight. The hydrophilic property can be imparted simply by applying the composition onto a member and drying or heating the composition applied to the member. The resultant hydrophilic thin film is transparent and, hence, does not sacrifice the transparency and appearance of a member required to be transparent. Further, the surface of a member with the above composition applied thereto has such a property that water droplets adhered thereon can be immediately removed by vaporization and the surface is less likely to be soiled and, even when a contaminant is adhered thereon, can easily release the contaminant therefrom.

Abstract: Cette invention se rapporte à un procédé visant à faciliter l'entrée de médicaments à l'intérieur de cellules et de tissus à des niveaux pharmacinétiquement utiles, ainsi qu'à un procédé d'apport ciblé de médicaments à des organites spécifiques de la cellule. Cette invention relative au ciblage de conjugués polaires lipidiques et de médicaments constitue un progrès par rapport aux autres procédés de ciblage de médicaments du fait que, conformément à ce procédé, les concentrations intracellulaires de médicaments peuvent atteindre des niveaux qui sont de très loin supérieurs à ceux obtenus par d'autres procédés. L'invention affine également le processus d'apport de médicaments en permettant de diriger des agents thérapeutiques vers certaines structures intracellulaires. Ce procédé convient aux médicaments antiprolifératifs, antibiotiques, antifongiques, antiviraux et antinéoplasiques, notamment lorsque ces médicaments sont utilisés en association à une multiplicité d'autres émollients et agents, et il peut servir à la fabrication de substances à activité topique telles que des onguents, destinées à permettre une introduction rapide et efficace de ces agents dans l'épiderme pour le traitement des dermatoses et autres troubles de la peau.

Abstract: A method and apparatus (12-20, 32) for automatically locating faults in a network of signal carriers (cables) utilises an interrogation waveform which is pulse-like in form and receives composite reflected signals from the carriers which are a time distributed collection of individual reflections.  These are sampled and compared using the function of an adaptive filter (52) to minimise the difference signal. The difference signals are analysed to determine significant points of departure which identify the fault location which is then represented as a distance value.
